Title:Modeling Melt Water Generation and Stream Flow Variability
in a Polar Desert, Taylor Valley, Antarctica
Antarctic Glacier Melt Water Modeling
Project Duration: 1-Aug-2003 - 31-Mar-2004

Michael Gooseff (Penn

are investigating the responses of stream flow variability (timing and
magnitude) to melt water generation on alpine glaciers in Taylor
Valley, Antarctica. We will utilize the extensive streamflow and
meteorological data collected over the past 10 years in Taylor Valley
for model input (met data) and verificaiton (hydrology data). The melt
water model that we will develop will be based on the Utah Energy
Balance Model [Tarboton and Luce, 1996].
Meteorological Station on the Taylor Glacier
1. Develop a spatially distributed energy balance model.
Apply this model to the Canada and Commonwealth Glaciers to reproduce
daily hydrographs from the 2000-01 and 2001-02 austral summer seasons
on a diurnal cycle for two streams from each glacier, each having a
distinctly different aspect [the glaciers longitudinal axes are roughly
NW to SE so we will consider the eastern most and western most streams
on each glacier].
Simulate seasonal ablation and its relative components (melt vs.
sublimation) with this energy balance model.
